To aZZ whom it may concern.'

Be 1t known that I, SALVATORE SANTINO,

a subject of the King of Italy, residing at' Chicago, county of Cook, and State of `Illinois, have invented certain new and useful Improvements yin Razor-floues, of which the following is a specification.

My invention relates to razor hones and the object of my invention is to provide a machine which will operate tol uicklyand efiiciently hone a razor, andithat y a simple back and forward motion of the hand.

In carrying out my invention I provide a stationary stone and a reciprocating carriage having a razor holder, and equip the device with means for pressing the razor into engagement with the stone vthroughout substantially the length of'the stone and means for turning the razor at the end of each stroke of the carriage.

My invention further includes means for regulatin the pressure'of the blade on the stone ant means for'adjusting the device to accommodate razors having blades of various thicknesses.

My invention further consists in means for adjusting the stone to accommodate razors of various degrees of thickness and to take up the wearof the stone.

My invention further consists in various details of construction and arrangements of parts all as will be hereinaiter fully described and particularly pointed out in the claims.

My invention will be more readily understood by reference to the accompanying drawings forming a part of this specification and in which,`

Figure 1 is a front elevation of va razor honing machine embodying my invention in its referred form, Fig. 2 is a plan View thereof, ig. 3 is a vertical transverse section on the line -gcf Figs. 1 and 2, the carriage being in central position, Fig. 4 is a erspective view of the carriage proper an a portion of the slides upon which it is mounted, Fig. 5 is a perspective view of the presser member, Fig. 6 1s a perspective view of the razor clamp, Fig. 7 is a slde elevation of the razor holding bracket, Fig. 8 is a rear clevation of the same, partially in section, the section being taken on the line 1/My of Fig. 7, Fig. 9 is a detail section onthcliae z-z of Fig. 2, Fig. l() is a detail vertical section on the line w-w of Fig. 2, Fig. 11 a detail sectional view on the line o-#v of Fig. 2, Fig. 12 is a diagram illustrating the operan tion of the presser member and Figs. 13, 14 and 15 are diagrams illustrating the operation of turning the razor at the end of the stroke.

Referring to the drawings 1 indicates the base of the machine. This is a plain rectangular member formed of any suitable material, but preferably of metal. Ifrom each endof the block 1 rises a standard 2. These may be formed separately and secured to the base 1 or if made of metal may be cast integrally therewith. Secured to the standards 2 near the top thereol, and extending from one to the other are a pair of parallel rods 8 upon which the reciprocating carriage' is slidably mounted.-

The carriage proper comprisesa rectangular oblong block 4. .This may be slidably connected to the rods or ways 3 in any suitable manner'but I prefer that illustratedin the drawings for obvious reasons. g As shown therein the rods pass through longitudinal assageways 5 provided for them in the block 4 and the passageways are enlarged as at 6 throughout the greater portion'of their length intermediate of the ends, to reduce the friction between the carriage and the rods. In. this manner the carriage is*i rovided with bearings for the rods at eac of the four corners.

7 indicates a knobor handle secured to the carriage -by a bracket or spider-8 and providing means for reciprocatmg the carriage.

Secured to the front of the carriage 4 is the razor holding device which comprises a bracket rigidly fixed thereto, a razor clamp, and a razor or clam holder depending from said bracket. The racket comprises a horizontal bar 9 arranged arallel with the front face of the carriage an connected thereto by a pair of arms 10. The razor clam comprises a cylindrical member 11 forme of the two semi-'cylindrical portions 12 and 13 secured together by a pair of screws 14. The members 12 and 13 are provided with registering longitudinal recesses 15 to receive the portion of the shank of the raZor adjacent to the handle and the contiguous portions of the handle, and thc reess in the portion 13 is deeper than that in the portion 12 in order to throw the back or rib of the razor in alinement with the axis of the clamp. The recesses 15'are preferably lined with rubber, cork orothergsimilar resilient material to hold the razor firmly without injuring the same. The razor clamp is rotatably mounted in a clamp holder secured to and depending from the bracket 9--10. The holder is a skeleton member consisting of the horizontal bar 17 arranged beneath and parallel with the bar 9, a pair yof depending arms 18 extending downwardly from the ends of the bar 17 -and having the bearing members 19 formed integrally therewith, a air of arms 20 extending rearwardly from the ends of theA bar 17 and a, depending U shaped member 21 the bottom 22of which forms bearings te support the clam near its inner end. It should be noted tat the bearings 19 at the forwardend of the clamp are arranged above the same and the bearing 22 at the inner end is arranged below'tho same. It is obvious that suitable fmeans'must be provided for 'supporting the outer or front end of the clamp. iscom'prises a semi-circular arm 23 pivotally connected to one of the arms 18 as at 24 and having its opposite end slotted f, as at 25 to receive a thumb nutas at 26 "threaded into the opposite arm 18.

The members 19 and the arm 23 form a complete circular bearing for the outer end of the clamp and a plate or iange 27 on the arm 23 forms a stop to prevent outward movement of the clamp. To insert or remove the clamp 11, the thumb nut 26 is loosened and the arm 23 dropped. After the clamp is in serted the arm 23 is raised into ositiapn. and the thumb screw tightened.' T e holder is vsecured to the bracket 9-10 bya screw 28.

'This is threaded into the bar 1f and passes through a bore 29 in the bar 9, through which it is free toreciprocate vertically. A spring .vided withdepending lugs 35 which are rilled. to receive said Y' ins. The bedr plate 33 .is provided .at'eac end with a lug 36 through which vis threaded a vertically dispos'ed screw 37 having a worm gear 38 formed thereon which meshes with a similar gear 39 on a shaft 4(1)l extending longitudinally .through .the base-1. The shaft 40 extends beyond one end ofthe base and is provided with a knurled h`ea141 by which it is turned.

By turning the shaft 40 the.. height of the arms 42 which terminate in the` oppositeljr extending horizontal portions or extensions 43, a short distance from the member 21 and parallel therewith. To the extensions 43 are secured a pair of spring arms 44-45 the former being secured to the upper face and the latter to the under face of their respective members 43. The inner or 'forward edges of the spring arms rest against the rear face of the clam 11 forming a stop therefor. The free ends o? overlap and the overlapping end are bent as shown in Figs. 8, 13, 14 and 1. "for reasons which will appear as the description proceeds wardly inclined portion 46 and .the downwardly inclined portion 47 andthe end of the arm 45 is provided .with the parallel portions 48 and 49, that is, the portions 48 and 49 are parallel with the portionsv 46 and 47 respectively of the arm 44. When a razor is in the machine the ortion of the Shank which extends beyonc .the clamp 11 is held between the portions 46 and 48 or the portions 47 and 49, and the angle of inclination the spring arms 44 and 45- The arm 44 is formed with the up' of these portions of the spring arms issuch as to normally hold the edge of the razor Aand for stroke preparatory for the next, also means for regulatmg the pressure. v

Vertically slidable in the block or carriage 4 through a verticall disposed aperture 50 therein is a block 51 t e lower end of which is bifurcated, forming the presser feet 52-52 one of which normally rests upon the blade of the razor.

are but a slight distance above the u per face of the stone 32 and rest against the. ack` or rib ofthe blade as will be seen by referring to Fig. v12. As the carriage is reciprocate the lever 53 shoves the blade with a steady movement and prevents any loose Alay thereof which would injure the edge o .the razor. A

55 indicates a cam-bar extending from end Pivotally mounted between the feet 521s a bent lever 53 the ends 54 of which to end of the machine and having its ends extending through vertically dis osed slots or guide-ways 56 in the upper e'n of the standhe lower edge of the bar 55 bears against a transverse lug` 57 formed on the upagace? per end of the block 51, and comprises a straight horizontal central portion 58 which is almost as long as the stone, a slightly elevated portion 59 at each end of Ithe portion 38 and a further elevated portion 60 at each end of the bar. When the presser member 51l1is beneath the portion 58 one of the presser feet 52 holds the blade, that is the edge thereof in engagement with the stone, .but as the edge approaches the end of the stone the lug 57 reaches the elevated portion 59 of the cam-bar which permits the presser member to rise, the spring arms 44 and 45 immedi ately raise-the edge out of contact with the stone. To raise the presser member I provide a pair of springs 61 interposed between a pair of lugs 62 on the presser member and the, carriage 4, the Walls of the a erture 50 bein" grooved or recessed as at 63 or said lugs an the bottom of said recesses being provided with the spring seats 64. To avoid having the member 51 extend above the carriage, the carriage is longitudinally grooved as at 55 to receive the cam-bar. The bar 55 rests .on the bottom 56 of slot 56.

To regulate the pressure of the blade upon the stone I provide means for regulating the pressure of the cam-bar on the member 51.

The ends ofthe cam-bar extend beyond or outside of the standards 2 and are apertured as at 65 to receive the vertically disposed rod 66 upon which the bar is vertlcally slidable. Upon the upper end of the rods 66 is threaded a washer 67. The washer l67 is above the4 bar 55 and interposed between the same is a spring 68. r The washer 67 is provided with a lug or tail 69 which extends into the slots 56 in the standards 2, preventing rotation of the same; It is obvious that by turning the rod 66 the pressure of the springs 68 uponthe cam-bar may be regulated. The lower end of each rod 66 is provided with a worm gear 70 which meshes with similar` gears 71 on a horizontal shaft 72 extending longitudinally of the machine.

. the clamp 11 is a spring arm '74 having i curved end 75, the curvature of which conforms substantially to the circumference of the clamp. As the clamp reaches the arm the end 76 of the arm engages a notch 77 in the eripheral faeeof the clamp after` which furt er movement of the carriage and clamp causes the latter'to be turned. This portion of the operation is illustrated in diagram in Figs. 13 to 15 inclusive. The notch 77 is normally a short distance below the horizontal plane of the axis of the clamp hence the arm slides under the clamp and causes it to rotate. When the end 76 of the arm passes beneath the center of the clamp it begins to rise on the o posite side and it is forthis reason that tie portion 75 is curved as described.` It should be noted that as the clamp turns and thereby turns the razor, the shank of the razor A is turned against the tension of the spring arms 44 and 45. Assuming that the carriage is movin0r toward the right hand end of the machine the shank of the razor will be held between the portions 47 and 49 of saidl arms, but as the clamp is turned the shank is turned' into the position. shown in Fig. 14 between the portions 46 and 48. As soon as the shank of the razor asses the vertical position, the resiliency or c amping action of the arms 44 and 45 uick y turns it into position for the next stro e, the notch 77 being then past center is disengaged from the end of the arm 74. In turning the razor the back or rib thereof passes under the arm 53 as shown in Fig. 12. This raises the presser member 51, and it is to permit the member to rise at this time that the end portions 60 of the cam-bar are elevated as before mentioned. the end 76 of the arms are at a suilicient dis- It should be noted that tance from the ends of the stone to prevent the edge ofv the razor engaging the stone when turning.

The spring arms 74v are preferably rigid but pivotally connected and spring pressed togive sufficient resiliency thereto. To this. end each arm is pivotally mounted as at 78 upon a post or standard 79 rising from the bed 1 near each end thereof and in front of the standards 2. l

Formedintegrally with the arms `74 is a flexible or spring arm 8() which extends vertically upwards with its free end held between lugs 81 at the to of the standards 79. This normallygf'holds tie armY in horizontal position and gives sufficient resiliency or spring thereto.

It is obvious that in pressing the razor against the stone, and in turning the same, the razor clamp must be free for a slight vertical movement and it is to this end that the clamp holder is supported by the spring 30. However it is evident that side or torsional movement of the clamp must be avoided and to this end the clamp holder is arranged to 'sfide vertically on the pins 82 depending' from the ends ofthe arm 9, the arms 18 being drilled to receive said pins.
